Title: Digital timing apparatus
IPC: G01M15/06
Filed: 1979-02-28
Abstract: The invention relates to a digital timing apparatus for measuring the phase relationship between a plurality of cyclically occuring events in, for example, an internal combustion engine. The apparatus has first means (74) for receiving and digitizing (eg forming a two state signal from) a cyclic continually oscillating reference signal having positive, negative and zero- crossover portions and for receiving and digitizing a plurality of timing signals, corresponding to the cylically occuring events, each timing signal having positive, negative and zero- crossover portions and second means (84) for displaying the phase relationship between a pair of the timing signals in terms of reference signal digits (eg number of high level states ocurring between them), in decimal format. A third means (86), is provided for measuring the period of the digitized reference signal as a proportion of the total cycle, and fourth means (88), coupled to the first, second and third means, automatically controls operation of the second and third means and causes the displayed phase relationship between the pair of timing signals and the period of the digitized reference signal to be compounded to provide a measure of the time between the pair of timing signals in terms of degrees of the total cycle. <IMAGE>

Title: Power Plant
IPC: F02C6/18
Filed: 1979-03-01
Abstract: A power process comprises a gas turbine process and a steam power process, characterised in that heat energy liberated by combustion of fossil fuels or by high temperature nuclear reactions is indirectly transferred, in a tubular furnace, to a gas mixture or gas-steam mixture under pressure p1, which mixture undergoes an endothermic chemical reaction, with increase in volume, on supply of heat in the temperature range of between 300 and 1,000 DEG C and under approximately constant pressure, the reaction products produced expand as the working medium in a gas turbine, and then undergo an exothermic chemical reaction, at lower pressures than p1 and lower temperatures, with decrease of volume, again at approximately constant pressure, to reform the original gas or gas steam mixture, so that after release of heat to a known steam power process, the gas mixture or gas-steam mixture or, after condensation of the steam constituent, the gas constituent of the mixture, can be mechanically compressed to the starting pressure p1 and can, after replacement of the steam constituent which may have condensed out, be recycled to the tubular furnace for repeating the cyclic process.

Title: Method of making printed circuit boards
IPC: H05K3/24
Filed: 1981-06-11
Abstract: A circuit board, copper-clad on both sides to 5 to 12 microns thickness, is drilled and the sides of the holes electrolessly plated with copper. The whole board is then electrolytically flash-plated with copper. A negative mask of a desired conductor pattern is printed on both faces and the conductor tracks and sides of the holes are copper plated to a slightly greater thickness than eventually desired. Selected areas of the tracks, including the walls and mouths of the holes are then electrolytically solder plated, using a second mask. Finally both masks are removed and the copper etched to remove the unplated parts of the initial copper layer and leave the desired tracks and holes which are through-plated with solder. As a modification, the circuit board is initially unclad and is subjected to the electroless and flash- plating steps after being drilled and coated with adhesive.
